“Capitalism was the only system in history where wealth was not acquired by looting, but by production, not by force, but by trade, the only system that stood for man’s right to his own mind, to his work, to his life, to his happiness, to himself.”
— Ayn Rand
🇰🇷 South Korea went from one of the poorest countries on Earth to a top-10 economy in a single generation.

No natural resources. No head start.

One mistake Africans make when it comes to money is that they do not maintain capital. They earn money and build a house, buy a car, help people in the village, throw parties. They do not keep capital, they do not collaborate with others who have capital. Ownership of capital is how keep wealth over the long run.
If 5 people can jointly field 1bn, they can make more from the 1bn together than if they each had 200m.
Always grow your capital, and collaborate with people who also have capital so you can join deals. And never be greedy - the bigger your capital, the safer your investment target should be.
Work with the same people for long - if you know a retailer who regularly needs 10s of millions for restocking, be their capital provider over years. You too will know the business, and you will have a good sense of how at-risk your capital is. Chasing new ideas is often poor.
Many people have technical knowledge or access, but lack cash to execute - if you see them do it 2-5 times, join them on the 6th time with 10% of their need, then 20%, etc. Try to never cross 30% financing, otherwise you are taking all the risk.
Keep your capital liquid when it is small and lock up in safe, interest producing assets when it is large.
Only ever buy private homes or cars from your interest - your wealth is not your capital, it's your interest.
Countries with more engineers grow faster. Countries with more lawyers grow slower. The cross-country data are striking. I'm a law professor, so make of that what you will.
